23 is YOUNG. You can still change your career path and be whatever you want to be. You just got to find out what you want in life & work towards that goal until you achieve it.

You don't need to quit your full time job to get a higher education. There are plenty of online, part time, and night courses you could take. You'll be tired as hell, but I guarantee it'll pay off in the long run.

You need to delete your facebook account & stop looking at what your peers are doing. That shit will just depress you. Who cares where other people are in life. Just worry about yourself.
